Severe anxiety and getting off medication?

Carina • 25 years young. baby #1 born April 11th 2017❤️
I'm 5weeks pregnant and my anxiety has been horrible ever since I stopped taking my meds 2 weeks ago (when I found out I was pregnant.) My first apt isn't until 08/14 so I don't know what's safe to take or do to calm me down. I feel like I may lose my mind by then which is horrible because I know stress can lead to miscarriage. My anxiety and my horomones aren't mixing well😢😔 Does anybody have any advise on what to do when coming off medication and pregnant? I was on Wellbutrin and xanax prior to my pregnancy. I want my lil bean to stick and to be healthy!👶✨
